Singular integral inequalities and stability of semilinear parabolic equations.(English)Zbl 0915.34057

The abstract Cauchy initial value problem given for $\tfrac {du}{dt} + Au = f(t,u), \quad u \in X, \qquad u(0)=u_0 \in X,$ is considered, where $$X$$ is an appropriate Banach space, $$A:X \to X$$ is a sectorial operator and $$f$$ has some more specific properties. Conditions are presented for the existence of a solution $$u$$ defined on $$[0,+\infty)$$ such that $$\lim _{t\to \infty }\| u(t)\| =0$$.
